Scientific Publications in Gastroenterology and Hepatology in Western Europe, USA and Japan in the Years 1992–1996: A Global Survey

Abstract

As randomly tested, the computer search had an error of +/- 5-10%. In Europe, Great Britain achieved the highest total impact factor and the highest number of papers. Most of the British impact factor came from publications in British journals. The total USA impact factor exceeded that of Europe by 20%. The average impact factor for a single paper was highest for the USA and, in Europe, for Germany. The temporal trend of total impact factor showed Spain improving by 9% per year, with Germany and Italy also displaying a substantial growth. Expressed per funds allocated in nondefense research and development, Great Britain and the USA had the highest cumulative impact factor.
